Uptime Kuma
MIT self-host uptime monitoring and status pages
Observability / Observability · OSS/MIT · 91k
What's Good
MIT. Docker-friendly (commonly on port 3001), monitors, notifications, public status pages. Zero SaaS lock-in for basic uptime.
The Catch
Self-host uptime + status pages — not Datadog/APM. You run the container, backups, and alerting path. HTTP/TCP checks are the lane, not full distributed tracing.
Verdict
MIT self-host uptime. Free forever; you own the box on 3001.
